[R] source, echo...and clicking the mouse

[Steven Wolf]

Ok, I think I see how flush.console() works.  Just put it in and whatever
has been done so far (and stored in the buffer) pops out.  Unfortunately,
I'm doing an optimization, and the process is slow.  So that is where the
"Misc|Buffered output" option is helpful.

Thanks!

The OP said he's running in Windows 7.  In that case, there's the
"Misc|Buffered output" option, which makes things appear as soon as they are
printed.  It appears to work for source(..., echo=TRUE) as well.
